Improve strength, posture, and coordination.
To tone and tighten your lower body, steal a move from charm school. The curtsy lunge works the major muscles in your hips, buttocks, and thighs, including the tough-to-target sartorii (the long muscles that run the length of your upper legs). And because it involves both strength and coordination, "this exercise will improve your posture and balance, too," says Cathe Thompson, a group fitness manager at Equinox Fitness in New York City, who created this workout exclusively for Real Simple.
